Abstract
A γ ray entering the atmosphere starts an extensive air shower based on e + e − pair production in the vicinity of an atmospheric nucleus and subsequent Bremsstrahlung radiation of e + e − pairs. We study the showers in which the deflection of the first e + and e − in the geomagnetic field causes the shower to split in two angularly separated components. Based on the Monte Carlo simulations of a subarray of Large Size Telescopes of Cherenkov Telescope Array we evaluate the expected rates of such events. We investigate the potential of a novel geometrical energy reconstruction of such events on the absolute energy calibration of Cherenkov telescopes.
